2.1. Materials and sample preparation
The epoxy system consists of a DGEBPA resin and a polycyclic
amine hardener ¡£Single-wall carbon nanotubes are added to the resin at 0.2 wt.% with the use of a three-roll-mill. The hardener is stirred into the resin-SWCNT
dispersion with a mechanical agitator and the resulting mixture
is put under a vacuum to eliminate air bubbles.
The samples consist of neat epoxy beams on which a layer of
strain sensitive SWCNT composite is coated. The beams are prepared
by casting neat resin specimens into aluminum moulds
and curing them for 1 h at 80 ¡æ. Subsequently, a coating of the
SWNCT¨Cepoxy mixture is applied to the surface of the epoxy at
an approximate thickness of 400 um and is cured for a further hour
at 80 ¡æ followed by 8 h at 140¡æ.
